Description	Abstract en In Monte Carlo simulations of electron swarms, sample electrons were copied periodically so that a sufficient number of samples are obtained in equilibrium after relaxation even under a severe attachment-dominated condition where most electrons vanish during the relaxation. The final sampling results were equivalent to those sampled by a conventional method, and the computational time conventionally wasted for the tracking of vanishing electrons was reduced drastically. The time saved can be utilized for tracking more samples to reduce statistical fluctuation. The efficiency of this technique and its limitation are discussed quantitatively together with details on its implementation. (C) 2018 The Japan Society of Applied Physics
